INSULATOR-SUPIORTING FIXTURE.

Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed. May 4, 1914. Serial No. 836,116.

a strong, inexpensive fixture particularly adaptable for supporting theconductors of high tension circuits and which can be read ily secured inplace, as for example on a pole, with a minimum of labor and expense andwithout the need of gaining the pole.

More in detail, the invention contemplates the construction of fixturesof pipe lengths rigidly secured together by strong and durable castingswhich are curved accurately fit the surface or" the supporting pole,

The various features of the invention are clearly shown on theaccompanying drawing in which-- Figure 1 is an elevational view of oneof my improved fixtures and one end of the pole to which the fixture issecured, and Fig. 2 is a top view oi the fixture and pole.

The fixture shown is of anchor shape comprising the vertical straightpart 5 preterabiy in the form of an ordinary pipe, and the U-shapedlower transverse part formed by the i--shaped brackets 6 and 6, the ends7 and 8 of which, and the end 5 of the part 5, are tapered and providedwith desired form of insuiator receiving thimbie 9, the thimbies shownin this case being in the form of wire helices To secure the parts o,

6 and 6 toge her i provide a fitting 1O pre erably in the form of acasting comprising a back a, a horisontai sleeve 0, and the verticallyextending sleeve or flange 6'. As

# shown, the unshaped parts 6 and 6' seat at their inner ends in theends of sleeve 5 and are securely heid therein by pins 11 and 11'. Thesleeve receives the lower end of the part 5 is secured therein by a pin12.

In order oo-secure the fixture to a support such as a pole p, aboltvhole 13 is provided through the fitting and through the part 8 forreceiving a bolt let. The part 5 above the fitting has also a bolt hole15 for receiving a bolt 16, and these bolts preferably extend entirelythrough the pole. In order that the fitting may more accurately fit thepole, the back of the base a of the fitting is rounded as shown in Fig.2. The fixture is preferably applied close to the top of the pole sothat the insulator supporting end of the part 5 will clear the top ofthe pole. After assembly of the fixture it is preferably galvanized bothinside and out and will then be efiicientl'y protected against theweather and its life greatly prolonged.

The fixture shown and described is of in-' expensive yet durableconstruction and its rounded fitting together with the through boltswill insure secure, rigid mounting thereof on the pole. Any kind ofinsulator support may, of course, be used for the insulatorsupportingends of the fixture or the ends of the fixture may be threadedor otherwise treated to directly receive insulators. instead of usingordinary pipe, solid metal or metal of any other shape may be used. I donot therefore desire to be limited to the precise construction, form andarrangement shown as changes may readily 'be made which would still comewithin the scope of the invention.

1 claim as follows:

1. An insulator supporting fixture com-v prising a vertical length ofpipe, a fitting to I which the lower end of said pipe is secured,bracket sections secured to and extending laterally from said fitting,the ends oi said bracket sect ons and the upper end of saidverticallength-being adapted to support insulators, there being a bolthole through said fitting and through said vertical pipe length forreceiving bolts to secure the fixture to a pole, the base of saidfitting being rounded to fit the pole surfaces.

3. An insulator supporting fixture comprising a pipe fitting having avertical socketend laterai sockets, a vertical pipe section secured atits lower end in said vertical 8001689, and L-shaped pipe sections se-In witnesswhereof, I hereunto subscribe my name this 27th day of April,A. D. 1914.
